  • Modular trial mechanism
    Patent number: 7828851
    Abstract: A prosthetic trial for a joint prosthesis includes a stem having a proximal section and a distal section for implantation in a bone. A body includes a channel receiving at least the proximal section of the stem. A locking mechanism is at least partially disposed within the body. The locking mechanism is biased into a locking position in which the mechanism locks the stem within the first channel of the body. The locking mechanism is accessible outside said body to be pulled into a releasing position to unlock the stem from the body.
    Type: Grant

  • PROSTHESIS WITH RESORBABLE COLLAR
    Publication number: 20070067042
    Abstract: An articulating hemiarthroplasty prosthesis (10) for use in arthroplasty is provided. The prosthesis includes a stem (12) for implantation at least partially within the medullary canal (14) of a long bone (16) and a collar (20). The collar (20) is operably associated with the stem (12) and extends outwardly therefrom. At least a portion of the collar (20) includes a resorbable material. The prosthesis includes a head (30) and a cup (46) for engagement with the head (30).

  • Prosthesis with feature aligned to trabeculae
    Publication number: 20050234560
    Abstract: A ball and socket joint prosthesis for use in arthroplasty is provided. The prosthesis includes a body for implantation at least partially within the medullary canal of a long bone. The long bone defines trabeculae in the proximal cancellous bone and lamellae in the cortical bone. The body includes a proximal portion thereof and a distal portion. The proximal portion has a medial periphery and includes surface features on a substantial portion of its proximal portion. The surface features are positioned to optimally transfer load from the prosthesis to the long bone.
